======Project -99: Logic Gates======

A project by Saad Malik for C/C++ Programming, Spring 2012.

=====Objective=====
The goal of this project is to make a program that will create logic gates. It does not accept inputs, but if you go in and change the course code accordingly, you will get the corresponding answer. For example, the and of 1 and 1 is going to be 1.

=====Code=====
This is a multifile program. I will display the .h and corresponding .cc files in sections.

====and====

====gate====
This header and .cc file is basically the parent class. Everything else inherits from this.

 12         bool A;
 13         bool B;
 14     private:
 15         bool X;
 16 };
 17
 18 #endif

<code c>
  1 #include "GATE.h"
  2

 14 {

 16 }
 17
 18 void GATE::setB(bool B)
 19 {
 20         this->B=B;
